At present, although the automation control system has made breakthroughs in foreign monopolies in major projects, it still needs more support.
In the series of “16 Major Concerns of Major Equipment†launched by China Industrial News in 2006, the director of the China Instrument and Meter Industry Association, Mr. Yu’s achievements, said that this is a special project for the development of major engineering automation control systems and key precision test instruments. It is to meet the needs of key construction projects and other major (complete sets) of technical equipment, which is highly automated and intelligent. It is an important part of implementing the "Several Opinions of the State Council on Accelerating the Revitalization of Equipment Manufacturing Industry".
At that time, the pattern of domestic automation control system and instrumentation industry was: middle and low-end products were mainly domestic enterprises, high-end products were mainly foreign-funded enterprises; large and medium-sized projects depended on foreign countries, and small and medium-sized engineering projects used domestic products. "In a sense, the automatic control system and key precision test equipment are becoming the bottleneck of China's equipment modernization." This is the summary of Qi Jiacheng at that time.
Today, Qi Jiacheng said that the automation control system has made breakthroughs in foreign monopolies in major projects, mainly in the fields of petrochemicals and electric power. However, the key precision test instruments are not obvious for various reasons, and further support is needed in the next step.
The automation control system project is progressing smoothly. The purpose of the major project is to break the monopoly of foreign large-scale equipment in the control and measurement of major areas including thermal power, petrochemicals, metallurgy, etc.†Jia Jiacheng recalled that the above-mentioned large-scale projects in key domestic industrial fields were basically Imported equipment is used. "When the thermal power unit was specially formulated, the 300,000 kW unit domestic equipment just entered, and the 600,000 kW unit was a foreign equipment."
Three years later, the automation control system project progressed well. According to the China Industry News reporter, there are currently 8 projects in operation, 1 has been completed, 2 have been accepted, and 5 will be accepted next year.
"The best implementation effect is the industrial control system of large thermal power." According to Qi Jiacheng, the current 600,000 kW domestic thermal power control system has been put into operation, and about 20 units have begun to adopt domestic systems. Thermal power 600,000 kilowatts and 1 million kilowatts large units are the mainstream of future development. Therefore, breaking foreign monopoly is of great significance to China's thermal power industry.
In terms of petrochemicals, Zhejiang Zhongkong undertook the control system for large refinery in October 2008. This is the first time that China's self-developed control system has entered the large refinery project. The large chemical fertilizer control system produced by the company using coal as raw material was successfully put into operation in Luzhou, Shandong. “If the control systems of the three fields of large refining, large chemical fertilizers and large ethylene can be independently developed, it shows that the high-end control system in the petrochemical field is autonomous.†Yan Jiacheng said.
In addition, important supporting technologies and equipment in the control system have also been developed. More typical is the transmitter. It is understood that the "high-precision intelligent pressure transmitter industrialization" project can be identified this year, in addition to nuclear power meters, process analysis special, actuator specials are in the implementation.
Control technology is the key technology to promote informatization. In terms of technical progress, Yan Jiacheng’s expression is “substantially equivalent to the international level.†For example, the error of the original domestic transmitter is 0.1%, which has now been reduced to 0.075%. This is the precision that international large multinational companies have.
"Our original principle has the same type of products, but it does not meet the country's requirements for large-scale engineering on indicators and reliability. Now, we achieve technological breakthroughs, mainly in the aspects of intelligence, digital, and integration." . However, he also admits that domestic equipment has insufficient experience in large-scale engineering applications, so the reliability and application experience are different compared with similar foreign products.
However, the benefits of technological breakthroughs remain significant. It is understood that before the mid-1990s, the price ratio of imported equipment to domestic equipment was roughly 3:1, even if users were reluctant to use domestic equipment. Now, the progress of domestic equipment has hardened the price of imported equipment. The current price ratio has dropped to 1.2 or 1.3:1. "Especially after the international financial crisis, the advantages of domestic systems have become more and more obvious. You can import equipment regardless of cost, but now you need to fully consider the cost factor." Yan Jiacheng said.
Qi Jiacheng believes that under the promotion of major special projects, "foreign control systems have broken the control and monopoly of China's important economic fields, and have responded to the independent innovation of the core technologies of measurement and control automation for industries such as power, petrochemical, metallurgy and building materials. Promote the role.†He said that the automatic control system and instrumentation are important equipments for informationization. The industrialization of information is the comprehensive result of the controllability of major equipment, the applicability of measurement and control equipment and the application of information optimization. Promoting informationization in the industrial field, control systems and control technologies are one of the key elements.
Occupation rate goal is difficult to achieve, need to increase support Although the implementation of major projects of the automatic control system has achieved the above results, but Jia Jiacheng still appeals, the state needs more support for this.
It is understood that the total investment of major engineering automation control systems and key precision testing instruments is 800 million yuan, while the state investment is about 100 million yuan. “There are few projects, small projects, and insufficient support.†Yan Jiacheng believes that the newly introduced equipment manufacturing adjustment and revitalization plan does not address the contents of automated control systems and instrumentation.
In the equipment manufacturing industry adjustment and revitalization plan, the attention of industrial automation control systems and key precision test equipment is not enough. "The original major projects should be combined with the current adjustment and revitalization plan."
The old problems of promoting applications still need to be addressed. According to Qi Jiacheng, companies in the current application field use less domestically produced equipment for independent innovation. Therefore, although the domestic equipment has reached the target, it takes time to promote and apply it. He believes that the guiding principle of independent innovation is to combine the manufacturing department and the application department, and the first (set) policy needs to be specifically implemented, and the competent department is clearly defined. “Technology and products have broken through. The project has been successful under the support of the state, and it has a certain production capacity. However, the application department does not actively create promotion conditions with the manufacturing department, and it will not play a major special implementation role.â€
It is understood that in the major engineering automation control system and key precision test instruments, it is very difficult to achieve the goal of achieving a domestic market share of 30% after ten years. "At the moment, it is just a breakthrough, but it is still not a share."
In addition, many of the current projects are in the field of automated control systems, and projects related to key precision instrumentation are not implemented. "Because the technical difficulty is higher, it is impossible to scale. In this case, the enterprise lacks support and the enthusiasm is not high." Yan Jiacheng initially estimated that if the key precision instrumentation project is implemented, it needs 30% to 50% of the state's financial support. Otherwise, even if the project is successful, the small amount and low profit will not make up for the investment of the company in the project.
